oracle rac启用归档模式

环境：

2个节点的RAC

数据库版本：12.1.0.2.0

目的：

启动归档日志，同时将归档日志存放到共享目录（我这里的是ASM磁盘组）

操作：

1、创建共享ASM磁盘组

C:\Users\Administrator>set ORACLE_HOME=E:\app\oraclehome\grid

C:\Users\Administrator>set ORACLE_SID=+ASM1

C:\Users\Administrator>asmcmd
ASMCMD> ls
DATA/
FRA/
OCR/
ASMCMD> cd fra
ASMCMD> pwd
+fra

ASMCMD> mkdir jiaxundb1
ASMCMD> mkdir jiaxundb2
ASMCMD> ls
jiaxundb1/
jiaxundb2/

2、查看目前数据库归档模式

C:\Users\Administrator>sqlplus / as sysdba

SQL> archive log list
Database log mode No Archive Mode
Automatic archival Disabled
Archive destination USE_DB_RECOVERY_FILE_DEST
Oldest online log sequence 89
Current log sequence 90
SQL>

3、设置归档格式以及归档目的地

SQL> alter system set log_archive_format='%t_%s_%r.arch' scope=spfile sid='*';

System altered.

SQL> alter system set log_archive_dest_1='location=+fra/arch/jiaxundb1' scope=spfile sid='jiaxundb1';

System altered.

SQL> alter system set log_archive_dest_1='location=+fra/arch/jiaxundb2' scope=spfile sid='jiaxundb2';

System altered.

4、关闭所有实例

C:\Users\Administrator>srvctl stop database -d jiaxundb

5、将实例1启动到Mount阶段，并设置数据库为归档模式

C:\Users\Administrator>sqlplus / as sysdba

SQL*Plus: Release 12.1.0.2.0 Production on 星期三 8月 17 15:27:20 2016

Connected to an idle instance.

SQL> startup mount

SQL> archive log list

SQL>

6、启动实例2，查看数据库归档模式是否正确

C:\Users\Administrator>sqlplus / as sysdba

SQL*Plus: Release 12.1.0.2.0 Production on 星期三 8月 17 15:35:30 2016

Copyright (c) 1982,

SQL> archive log list
Database log mode Archive Mode
Automatic archival Enabled
Archive destination +FRA/arch/jiaxundb2
Oldest online log sequence 76
Next log sequence to archive 77
Current log sequence 77
SQL>

7、切换日志组，验证日志是否被成功归档

SQL> alter system archive log current;

System altered.

ASMCMD> ls jiaxundb1
1_90_914678682.arch
1_91_914678682.arch
ASMCMD> ls jiaxundb2
2_77_914678682.arch
2_78_914678682.arch

OK，实例1和实例2已成功归档。
